What people say

Spinnaker Hull California (Olive Oyl Red)

Owners widely praise the Spinnaker Hull California (Olive Oyl Red)'s polished case finish and textured dial, with one owner finding its jubilee bracelet superior to Seiko's. Some find the 24-hour subdial functionally illogical and visually unappealing, while others prefer a smoother dial texture over the current finish. On balance, owners value the Spinnaker Hull California (Olive Oyl Red) for its striking dial and high-quality bracelet at its price point.

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package.

Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.
